The invention has for its general objects Yto improve the construction of wheels whereby one Wheel on an axle will be loose for permitting the twowheels to have differenti'al movement for freely passing around a curve in the track,.the wheel being preferably cast of manganese steel and provided with a bushing which is forced or diliven into the hub portion of the wheel and which freely rotates on the axle,-there "being a special formation whereby the'bushing is engaged with a retain ng ring or collar fastened to the axle bearing, whereby the wheel can be reniovably applied to the axle. v v

lVith such objects in view, and others which will appear as the description proceeds, the invention comprises various novelfeggtures of construction and arrangement of 80' parts which will be set forth with partieu-' larity in the following description and claims appended here-to.

illustrates one einli odiinent of the invention '85 and wherein similar characters of reference I indicate corresponding parts in both the views, Figure 1 is a sectional view of the wheel and associatedparts; and Fig. 2 1s a sideview of the wheel.

Referring to the drawing, A designates the car wheel, B the axle, C the bearing therefor; and D the wheel-retaining ring. The wheel A in the present instance is supp'osed.to be cast ofmanganese steeh which metal is too hard to admit of the .bore of the hub being finished in such ainanner as to have a rotating contact with the axle B, and therefore, in' the hub 'l of the wheel is disposed a brass, bronze or other bush- 'ing 2 of such vshape and size as to have a forced lit in the'hub, making the bushing.

and wheel a permanently united unitary K structure. This bushing has its bore careifully'rnachined so as-to fit the axle on which the wheel rotates. The inner end of the bushingis slightly larger in diameter than Specification of Letters Patent.

the bore of the hub so as to forni ashoulder againstwhich the'hub engages when the bushing 15 dr ven 1nto the hub, and beyond projects over the inner end of the bushing and has an internal annular flange or the equivalent 7 which engages in the annular groove 5, whereby the wheel A and the bushing are retained on the axle. T he retaining ring it made in one piece is applied to the bushing before the same is driven into the wheel, and the wheel is fastened in place by screwing the retaining ring on the bearing with the end of the axle projecting into the bushing 2.

closed and a chamber 9 is formed between the closed end of the bushing and the axle to contain lubricant, which is supplied through a normally plugged opening 10 in.

Fro-n1: the foregoing description taken in connection w th the accompanying'drawing,

the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while I have de- Y Y v s'cribed'thc principle of oper'ation, together 4 In the accompanying drawing, which i with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that-such changes may be made when desired as fall within the seopc of the appended claims. v

Having thus described my invention, '1 claim as new and desire to secure by Letters Patent: 7

1. The combination of an axle, a bearing therefor a retaining ring reniovably fastened to the bearing and having an internal flange, a wheehand a bushing fastened in the hub of the wheel and having an annular groove on its inner end with which the flange of the retaining ring engages to rotatably hold the wheel and bushing on the axle.

The combination of a wheel, a bushing fastened in the, hub thereof and having an end extending from one end thereof, said extending end being formed with a' circumferential'groove, an axle extending into the bushing, a bearing for the axle, and a ring The outer end 8 of the bushing 2 mean:

screwed on the outside of the bearing and embracing the prejeeting end ofthe bushing and formed. with an interned unnuhr flange engaging in the groove of the bushing to rotutubly retain the latter and wheel on the axle.

In testimony whereof 1 have signed my name to this specification in the presence of two subscmbmg \VltHCSSGS.
